Question

我正在学习spring ioc / struts2，并且我不断得到NoClassDefFoundError。正确的罐子放在我的pom文件中，所以我很迷惑。在this advice之后，我将有问题的jar添加到我的bootstrap条目中，并且它摆脱了那个特定的NoClassDefFoundError，但我遇到了另一个。

我一直在为我的引导程序条目添加jar，这似乎解决了出现的每个问题，但我想确保我实际上解决了我的问题，而不只是在上面放了一个bandaid。

这是当前的引导程序条目：

bootstrap entries

下面是我的pom和我最近的堆栈跟踪。

提前感谢。

Answer 1

java.lang.NoClassDefFoundError表示类路径中类的运行时版本与 compile 时的类不同。

您的堆栈跟踪没有ClassNotFoundError - 所以您的问题可能是在部署服务器时找到的类的多个版本。 ListableBeanFactory是spring-beans.jar

的一部分

您是否可以搜索在运行时服务器环境中找到的spring-beans.jar的版本数量，即在Tomcat中作为您添加的boorstrap的一部分，以及在您自己的WEB-INF下的webapp库中？
可能有多个或版本相互冲突。

看起来你在IDE中运行Tomcat，在这种情况下你必须在正确的位置搜索。

Answer 2

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.2.3.RELEASE</version>
</dependency>

你似乎错过了来自this stackoverflow问题的spring-beans。

来自tomcat的NoClassDefFoundError。我的pom有问题吗？
